BACK-REST FOR SEATS.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed September 20, 1915. Serial No. 51,530.

To all whom it may concern Be it known that I, HOWARD W. WEED, a citizen of the United States, and a resident of Stamford, in the county of Fairfield and State of Connecticut, have invented a new and Improved Back-Rest for Seats, of which the following is a full, clear, and exact description.

This invention relates to seats and has particular reference to resilient back rests therefor.

Among the objects of the invention is to provide a back rest for seats such as the saddles of bicycles, motorcycles, or the like, such back rests being movably connected to the seat frames or supports so that they may be swung downwardly out of the way for mounting upon or dismounting from the seats.

lVith the foregoing and other objects in view, the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a side elevation of a preferred embodiment of the invention shown as applied to a cycle seat, parts being broken away and dotted lines indicating the back rest in lowered position; Fig. 2 is a rear elevation of the same; Fig. 3 is a plan view; and Fig. 4 is an enlarged vertical sectional detail on the line ll of Fig. 3.

Referring more particularly to the drawings, I show a saddle 10 which may be regarded as typical of any suitable seat to which the back rest may be connected, said saddle being supported upon a frame 11 attached to a seat post 12. The saddle, furthermore, is stiffened and reinforced at its back end by means of a metal plate 13 to which the hangers 14 are connected at their upper ends and supported at their lower ends upon cushioning devices 15 of more or less conventional form.

The frame 11 comprises two horns 16 which diverge rearwardly and downwardly from the head 11 and terminate in a pair of loops or shoulders 17 lying in the same horizontal plane and projecting outwardly from each other. i

The back rest comprises a bar 18 typifying turned ends 22 of a pair of divergent arms 23 pivoted at 24 to the front ends of the frame members 16 on a horizontal pivot. The extreme front end of the arm structure constitutes a handle 25 adjacent which is pivoted a finger piece 26. Adjacent the plate 13 the arms 23 are provided with pivoted hooks or dogs 27 pivoted at 28 and connected by rods 29 extending forwardly therefrom to said finger piece 26. Each dog is acted upon by a spring 30 to force the same rearwardly into locking engagement with a catch 31 secured to the rear portion of the seat.

The person seated upon the seat 10 has control of the position of the back rest through the handle 25 and finger piece 26. In order to dismount from the seat with facility, the operator will grasp the finger piece and pressing it toward the handle will withdraw the dogs 27 from the catches 31 against the force of the springs 30, setting thereby the back rest free to drop toward the shoulders 17. The form and arrangement of the several parts are such, however, that the arms 23 instead of dropping forcibly upon the shoulders will strike against the horns 16 at points between the head 12 and the shoulders 17, thereby checking or cushioning the falling impact. The arms 23, however, are adapted to move downwardly either by gravity or by slight additional force until they rest upon the shoulders 17 At this time the cross bar 18 is outside or below the level of the seat. After mounting upon the saddle, the operator may lift the back rest either by upwardly lifting directly thereon or by pushing downwardly upon the handle 25, when the dogs will snap over the catches and positively lock the back rest in position. The form of the dogs and catches is such that it is impossible for the dogs to be released from the catches accidentally.

I claim 1. The combination with a seat and its supporting frame, of a back rest comprising a pair of arms pivoted to the front portion of the frame and movable downwardly with respect to the seat, and" devices cooperating between the rear portion of the seat and 'said arms to lock the arms in elevated posioted locking means carried by the arms cooperating with holding means secured to the rear portion of the seat serving to prevent the downward movement of the back rest toward the shoulders, and means at the front portion of the back rest arm structure to controlthe position of the back rest.

3. In a device of the character set forth,

. the combination with a seat and a support- 1 ing frame therefor comprising downwardly and rearwardly diverging horns terminating in stop shoulders, of a back rest comprising a pair of arms connected by a hori- Zontal. pivot-adjacent their front ends to the frontportion of the frame and movable downwardly along said horns toward the shoulders, said back rest also including a Copies of this patent may be obtained for resiliently supported cross bar located normally above the seat, and movable devices carried by said arms cooperating with the back portion of the seat serving to hold the back rest in operative position.

4:. The combination with a seat, a supporting frame therefor including a pair of rearwardly and downwardly diverging horns terminating in outwardly projecting stop shoulders, and a pair of hangers connected at their upper ends to the seat and supported at their lower ends from said shoulders, of a back rest comprising a frame pivoted at its front end on ahorizontal pivot to the front portion of the supporting frame and supporting at the rear end a cross bar, said frame being movable downwardly along said horns and adapted to be limited in such movement by said shoulders, and means cooperating between the frame and the seat normally preventing such downward movement of the back rest.
